Description

RXS

6:1

RX Size

This field specifies the Kbyte threshold for transmitting the PAUSE frame.

As the received FIFO is occupied than or equal to this field, the PAUSE

frame is sent automatically by HW.

If this field = 2, as receive FIFO is occupied more than or equal to 2 Kbyte,

the PAUSE frame is transmitted.

FCRXS

Description

EP1S0E

EP1 Send

DEP1, Disables EP1 send 1-byte 00 function

EEP1, Enables EP1 send 1-byte 00 when more than frame_

interval’s NAK is received

FID

6:5

Frame Interval Detail

This value is the detailed scale of frame interval, it is from 0ms to 3ms.

00B , for more than 0 plus frame_interval ms NAK, EP1 sends 1-byte 00

01B , for more than 1 plus frame_interval ms NAK, EP1 sends 1-byte 00

11B , for more than 3 plus frame_interval ms NAK, EP1 sends 1-byte 00
